Rogues are in a pretty good place in Cataclysm in both PvE and PvP. We don't see a lot of huge glaring problems that need to be fixed. I realize there are several players out there asking for change just because they're getting bored of the same class or at the very least wanting to spice it up, and that is a totally valid way to feel. But you also have to consider the risk we'd take for all of the rogues out there who are totally happy with the way their class is playing now, thank you very much.
As an example, we changed paladins in Cataclysm because we thought they needed a resource mechanic to make their gameplay more interesting. Overall we're happy with the way that has played out, and it's even better in Mists, but it's also very easy to find "please remove Holy Power" posts regularly. While we disagree with those players, the fact remains that we made the class worse for them.
To use a second example, we are changing warlocks pretty extensively for Mists because we thought they had several fundamental problems. Is every warlock going to like those changes? Of course not. Are there going to lots of players who beg us to revert the changes? Absolutely.
(And this is all ignoring the risk that even changing a mechanic from an acknowledged bad design to a good design still risks frustrating or annoying many players just because they have to relearn something.)
We are trying to fix some of the annoying things rogues have had to deal with and we are trying to offer some options in talents and glyphs that can help spice up the gameplay for someone who has been loyally Finsterer Stoß
ing for these eight years. But we also don't want to fix what isn't broken. We try really hard not to change classes for the sake of change. It's hard. But we try.
I'd go as far to say that most of the class team would probably agree (and I didn't poll them, so I may be sticking my neck out) that the rogue is the best designed class. And much of that design was in place before virtually any of us started working on classes, so we can't even really take credit for it. The rogue has the best resource system (energy), a strong kit, a good toolbox, and a clear role in PvP and PvE, yet it still has disadvantages to go along with the advantages and can't just do everything flawlessly all the time. It's a good design, again in our humble opinions, which is why you see so few changes to the class overall. But please don't over-read that as my stating that we won't fix bugs, add polish, balance numbers, undo bone-headed design flaws when the need arises, or yes, add a little bit of newness once in awhile just to keep things shiny.
What annoying things have we had to deal with that you're fixing?
